Dear

as you can check here: https://knowage-suite.readthedocs.io/en/7.2/installation-guide/requirements.html

Knowage is certified on JDK 1.8, and we are going to start the certification process on JDK 11, but now you have to use JDK 1.8

I think your issues is related to this aspect, chek and let me know.

If this doesn't solve, write me more detail about your installation steps.

Best Regrads
